I know it's not out yet, but I'm wondering if GarageBand will, after recording a live instrument, allow you to cut and paste it at will. In other words, can I record a guitar part, then clip out parts of it, splice parts together, move parts around, rearrange, etc? It sounds silly to wonder about, but it wasn't demonstrated during the MacWorld presentation. The iApps tend to have unusual limitations when compared to their professional-level counterparts, so who knows. I thought I'd throw the question out there anyway.
